Celanese Corporation Announces Change in Pension Accounting

Celanese Corporation (NYSE: CE), a global technology and specialty materials company, today announced its plans to change its accounting policy for its defined benefit pension plans and other postretirement benefit plans (collectively, "Plans"). Under the new accounting policy, referred to as mark-to-market ("MTM") accounting, the company will recognize actuarial gains and losses and changes in the fair value of the Plans' assets in operating results in the fourth quarter of each year rather than deferring and amortizing them into future years. This change is effective January 1, 2013 and is retrospectively applied to the company's financial results for all periods presented in its Current Report on Form 8-K submitted today.

"We believe this accounting change will provide investors with greater transparency into our operating results and will allow investors to better evaluate our underlying operating performance since our Plans' investment gains and losses as well as interest rate changes will be recognized in the year in which they occur, rather than amortizing them over future periods. This accounting policy change will not impact benefits received by participants of these Plans or related funding obligations," said Steven Sterin, chief financial officer.

As a result of the retrospective application of this change in accounting policy, Celanese earnings per share from continuing operations for 2012 decreased from $3.81 to $2.35 primarily due to the fourth quarter MTM adjustment of $389 million. Excluding the MTM adjustment, Celanese adjusted earnings per share for 2012 increased from $3.80 to $4.07 on lower amortization of prior period actuarial losses of $53 million.

The company does not expect the retrospective application of this change in accounting policy to impact the company's previously communicated growth rate for adjusted earnings per share in 2013.

In connection with this change in accounting policy and to properly reflect actual operational expenses of each business segment, the company will change its allocation of net periodic benefit costs. The company will now allocate only the service cost for active employees and amortization of prior service cost components of its Plans to its business segments. All other net periodic benefit cost components will be recorded as Other Activities. The components of net periodic benefit cost that will no longer be allocated to each business segment include interest cost, estimated return on assets and net actuarial gains and losses as these components are considered financing activities managed at the corporate level. The company believes the revised expense allocation will more appropriately match the cost incurred for active employees to the respective business segment.

Reconciliation of Non-U.S. GAAP Measures to U.S. GAAP

This release reflects the following performance measure: adjusted earnings per share as a non-U.S. GAAP measure. This measurement is not recognized in accordance with U.S. GAAP and should not be viewed as an alternative to U.S. GAAP measure of performance. The most directly comparable financial measure presented in accordance with U.S. GAAP in our consolidated financial statements for adjusted earnings per share is earnings per common share-diluted.

Use of Non-U.S. GAAP Financial Information

• Adjusted earnings per share is a measure used by management to measure performance. It is defined by the company as earnings (loss) from continuing operations, adjusted for other charges and other adjustments, and divided by the number of basic common shares, convertible preferred shares and dilutive restricted stock units and stock options calculated using the treasury method. We may provide guidance on an adjusted earnings per share basis and are unable to reconcile forecasted adjusted earnings per share to a U.S. GAAP financial measure without unreasonable effort because a forecast of other charges and other adjustments is not practical. We believe that the presentation of this non-U.S. GAAP measure provides useful information to management and investors regarding various financial and business trends relating to our financial condition and results of operations, and that when U.S. GAAP information is viewed in conjunction with non-U.S. GAAP information, investors are provided with a more meaningful understanding of our ongoing operating performance. Note: The income tax rate used for adjusted earnings per share approximates the midpoint in a range of forecasted tax rates for the year. This range may include certain partial or full-year forecasted tax opportunities, where applicable, and specifically excludes changes in uncertain tax positions, discrete items and other material items adjusted out of our U.S. GAAP earnings for adjusted earnings per share purposes, and changes in management's assessments regarding the ability to realize deferred tax assets. We analyze this rate quarterly and adjust if there is a material change in the range of forecasted tax rates; an updated forecast would not necessarily result in a change to our tax rate used for adjusted earnings per share. The adjusted tax rate is an estimate and may differ from the tax rate used for U.S. GAAP reporting in any given reporting period. It is not practical to reconcile our prospective adjusted tax rate to the actual U.S. GAAP tax rate in any given future period.

Results Unaudited

Quarterly results should not be taken as an indication of the results of operations to be reported for any subsequent period or for the full fiscal year.
